Omega 3 : walnuts!

As somone who doesn't like fish, I'm aware I'm missing out on the most mentioned source of Omega-3. I like to think (perhaps through simple self-serving rationalization) that at least I'm also missing out on the cumultative heavy metals and pollutants often found in fish - something which actually might also be an issue with fishoil supplments.
But what I didn't realise is that walnuts are actually a much better source, with a single 1/4 cup serving provides nearly all the 'daily value' required, and this is 1.5 times the amount of Omega-3 as a serving of salmon.
So hope for us pescaphobes!

Note : a walnut half (~2g) contains ~.15g Omega-3. The omega-3 DV (for an adult male) is ~1.6g per day. This means a daily intake of ~6 walnuts should provide the DV of omega-3 (as a side note, 6 wlanuts contributes approx. 150 calories)

(this matches the advice on "walnuts.org" :
Studies have shown benefits of eating 1 to 1.5 ounces of walnuts (14-21 halves) on heart health, bone health and in managing type 2 diabetes (link to health study page on walnuts.org).  In fact, due to the strength of evidence supporting cardiovascular health, the U.S. Food and Drug Administration approved a qualified health claim for walnuts in March 2004 stating “eating 1.5 ounces of walnuts per day, as part of a low saturated fat and low cholesterol diet, and not resulting in increased caloric intake may reduce the risk of coronary heart disease.”)

WHFoods: omega-3 fatty acids

The following chart shows the foods that are either an excellent, very good, or good source of omega-3 fats. Next to each food name, you'll find the serving size we used to calculate the food's nutrient composition, the calories contained in the serving, the amount of omega-3 fats contained in one serving size of the food, the percent Daily Value (DV%) that this amount represents
